Etymology
the word "debunk" is a 20th-century american coinage, a blend of the prefix "de-" and the colloquial term "bunk." the prefix "de-" derives from latin, carrying the sense of removal or reversal. "bunk" itself is a clipped form of "bunkum," which originated from a nonsensical speech given by a representative from buncombe county, north carolina, in the early 19th century, and came to signify empty, insincere talk. thus, the literal construction of "debunk" is to "remove the nonsense," logically evolving into its modern meaning of exposing falsehoods or exaggerated claims.
